Fake it till you become it

Something I think i'm reallly good at is singing which I'm really passionate about. I've been singing since I was speaking full sentence. I just know that I love singing and that its a big aspect in my life. But something that I need more confidence in is Math, I always feel as if im the dumber one in the class cause I don't know so much, Or I don't understand as well as the other. In conclusion I think I'm pretty good at singing and I think im decent at math.
